LUBRICATOR.

Application filed July 27,

My invention relates to lubricators such as are especially adapted for use in railroad rolling stock journal boxes, and consists in a pumping means and a conduit or passage for the pumped lubricant to the surface of the journal to be lubricated. In Patent No.

1,265,198, issued to me May 7, 1918, I disclose a lubricator in which the lubricant is fed to the journal by the inertia of members rolling on the bottom of the lubricant reservoir. 1 i 1 One object of my present invention is to improve upon this inertiaoperating means by providing a pump operated by inertia thereby securing a more positive and elficient supply of lubricant to the wearing surface.

Another object of my invention is to provide a flexible conduit for the lubricant from the surface of supply to the surface to be lubricated and to deliver the lubricant uni formly to a substantial area of the journal independently of va'riations in the position of the journal in the journal box.

In the accompanying drawings which illustrate a selected embodiment of my invention,-

Figure 1 is a longitudinal section through my lubricator and showing aportion of a journal to which it is applied.

Figure 2 is mtransverse section through the lubricator and journal The body 1 of the lubricator comprises a reservoir which is adapted to be seated in the journal box (not shown) and is provided with an integral pump cylinder 2 and pump delivery barrel 3, the former extending horizontally and located near the bottom of the reservoir, the latter extending vertically from the inner end of thepump cylinder to a point well above the height of the lubricant in thereservoir. A ball 4 serves as a check valve in barrel 3 andthe lubricant is forced through cylinder 2 past ball 4 by means of a plunger 5, the construction and operation of which is detailed in my copending application Serial No. 578,018. The plunger is preferably operated by a reciprocating movement of a block 6 of wood or other ma teria'l adapted to float upon the lubricant in the reservoir and of an area which permits to have substantial movement lengthwise of the reservoir.

Block 6 is provided with a central opening 7 which fits over barrel 3 and prevents limitation of the movement of the block. Block 6 is connected to plunger 5 by a! stem 8 rigidly 1922. Serial no. 578,019.

attachedto plunger 5 and having an elongated bearii g in block 6 upon which the block may slide vertically when it rises and falls with the surface of the lubricant. There 18 no free play betw'eenfthe block and stem plunger is increased andwhene ver the latter action takes place, a portion of this lubricant is forced up intobarrel 3. The upper end of barrel is fitted with a member 9 having a circular opening in its side 10. A hollow hall 1.1 is positioned in member 9 and seated against the opening in side why a coil spring 12.

forms a projection 14 which extendsupwardly and terminates in a trough 15'wh1ch ex tends longitudinally of the journal throughout a substantial portion" of the length of the latter, thereby being adapted to supply lubricant over a considerable area.

I prefer td equip my lubricator with waste packing such as is in general use and to support the same I provide a cage16 of sheet metal' theupper edges o f'which are adapted to fit the lower portion of the journal to which the lubricator is ap plied and the bottom of which surrounds barrel '3 and is yieldingly supported by a coil spring 17. Trough 15 is yieldingly maintained against the surface of the journal A by a spring 18 here shown as acoil compressed between member 14 and the bottom of cage 16. [The side 10 of member 9 isfpreferably screwed v "The inner face of ball 11 is provided with an inlet 18 and the outer-face thereinto or otherwise made removable to facilitate the insertion-of member '11. Obviously the ball and socket joint provided by this construction enables the trou gh to follow journal A in every shiftin'gniov'ement of the latter without losing any lubricant which may be present in member 9 or in the trough. Thetendency of wear on the edges .of the trough is such as to improvetheir contact with the face of the journal.

A series of overflow holes 19 are provided in the side of trough 15 above the edge of the lower side of the trough. Through'these holes lubricant is supplied through the waste contained in'eage 16and hack pressure up on the pump or pump passages iselunlnated. By means of this construetlonthe Oil or other lubricant is pumpedndireetly to the journal instead of being applied thereto only through waste which may fail to contact with the journal or inaybecoine hard the waste; that is, with the direct supplg of lubricant to the journal inuch less work required of the operating mechanism? Obviously the details of construction of my lubricator may be varied without'departing from the sp1r1t of any nvention as e::-
